NECK AND COVER FOR CLOSING BOTTLES OR JARS.

SPECIFIGATIQN forming part of Letters Patent No. 699,606, dated May 6, 1902.

Application filed October 1, 1901. Serial No. 77,205. (No model.)

To all whom it may concern:

Be it known that I, ALLEN F. WILsoN, of Clayton, in the county of Gloucester and State of New Jersey, have invented a new and useful Improvement in the Necks and Covers for Closing Bottles or Jars and Like Vessels, of which the following is a specification.

This invention relates to that class of bottles and jars which are closed by a cap having a packing of soft lining contacting with the end of the neck, and particularly to that class in which two or more helical project-ions in the cap engage with segmental projections on the bottle-neck and by a partial rotation of the cap enforce fluid-tight closure of the packing against the end or lip of the neck.

My invention has for its object the easy and prompt production of such bottles of uniform dimensions of all parts involved in the closingfunction; and to this end it consists in forming short circumferential segmental projections upon the neck of the bottles with larger intervening spaces in combination -with a cap having longer segmental helical internal projections adapted to engage the projections on the bottle-neck, with shorter segmental spaces between the helical projections, through which shorter spaces the projection in the neck can pass in applying the cap to the neck. By means of this construction of parts I am enabled to mold the bottle neck and lip with the projections of such uniform dimensions and with a fire-finished or fused lip, to which caps may fit interchangeably without fitting of packings or selection for each bottle and to avoid the expense of grinding the ends of the bottle-necks to a form adapted to fit packings and caps. The tool or apparatus for making such bottle-necks is the subject of another application forLetters Patent, Serial No. 77,206, filed October 1, 1901.

My invention is shown in the accompanying drawings, in whioh-- Figure 1 shows a plan or top view of a bottle neck and cap in closed position. Fig. 2 is a side elevation thereof. Fig. 3 is a verti- Fig. 4 is a detached View of a cap in inverted position.

Fig. 5 is a vertical section thereof, and Fig.

0 is a plan view of a bottle-neck embodying my invention.

Referring to the drawings, (t represents the neck of a bottle; I), a bead formed thereon; c, the lip or upper end of the neck.

(Z (Z (Z are short equidistant segmental proj ections formed externally on the neck Ct, with larger segmental spaces 6 e 6 between them.

f is the cap or cover, having a recess or space g for receiving a cork or other compressible packing 7t.

Projecting inwardly in the cap f are three helical segments 7t 7t 7b of such length as to pass downward through the spaces 6 66 between the segments d cl d, and of such diameter and pitch as by partial rotation to engage under the segments (1 d d and draw the cap f down and compress the packing g into fluidtight contact with the lip c. The lower sides of the projections cl d d are in the same circumferential plane and are therefore susceptible of being finished by rotation against a forming-tool, while the other surfaces and the lip of the bottle are formed by being pressed into a mold and are therefore of uniform size and form, and the lip c is a finished fused surface or fire-polished.

The segmental projections 70 h 7L in the cap f are helical, and after passing downwardly between the segments d (Z d through the spaces 6 c e by turning engage under the projection d (l d and draw the cap f down, compressing the packing 9 into fluid-tight con= tact with the lip c.

Having described my invention, :what I claim is- In a device for closing bottle and jar mouths, a neck having three equidistant short circum ferential segmental projections and a firepolished lip, in combination with a .cap having a packing and corresponding longer in ternal helical projections, adapted to engage said short projections and center the cap on the neck and compress the packing into fluidtight contact with the lip substantially as set S.
